Big Gull Lake has two public boat launches maintained by the Township of North Frontenac, situated at opposite ends of this roughly 12-mile-long lake in the southern portion of the North Frontenac Parklands.

One launch is located at the end of Thompson Road and the other at 1044 Helen Lane. No road permit is required to access Big Gull Lake, though overnight camping at the boat launches is prohibited under Township by-law.

The launches provide access to a lake known for fishing — Northern Pike, Walleye, Largemouth Bass, Smallmouth Bass, and Perch are all present — as well as paddling and camping.

The lake's 25 backcountry campsites, many situated on islands, are accessible only by watercraft, making the boat ramps the primary gateway for visitors. Users are advised to park without blocking access for others and to observe all posted signs.
